Which of these would be a good use case for a custom policy?

A custom policy allows you to define specific rules for how your content is handled on YouTube, offering granular control beyond standard policies. In this scenario, monetizing short fan-uploaded clips while blocking longer ones is a perfect use case for a custom policy. You can set a duration threshold (e.g., 30 seconds) within the policy to automatically monetize clips under that length and block or track those exceeding it. The other options are less suitable for a custom policy: Monetizing cover songs but blocking parodies would typically involve manual review or more complex content ID matching, as distinguishing between the two algorithmically is challenging. Monetizing viral videos for 30 days is a time-bound action that might be managed through standard policy adjustments or manual intervention rather than a persistent custom policy. Issuing takedowns based solely on upload origin (e.g., China) is generally not a standard or recommended practice for content management and could have legal or ethical implications.
